2.2 Cleaning, Disinfection, and Sterilization

2.2 Cleaning, Disinfection, and Sterilization

NIC Domain 1.A.2 asks you to recognize the purpose of infection-control principles, including three levels: sanitation/cleaning, disinfection, and sterilization. New Jersey shop law does not use those three CIB words as three separate license duties. N.J.A.C. 13:28-3.2 is titled Sanitizing implements and tools, and it describes one required sequence: clean, rinse, then either chemically disinfect with an EPA-registered tuberculocidal product for the labeled contact time or sterilize in an FDA-registered autoclave, then air-dry and store in a clean drawer. If you treat sanitize as if it meant wipe with soapy water, you will fail both the NIC level question and the New Jersey law question.

The three CIB levels

Cleaning (the CIB also says sanitation/cleaning) is the removal of visible debris, soil, and organic matter from a surface. You wash. You do not yet claim the item is safe for the next client. Soap or detergent plus water — New Jersey specifies a mild alkaline detergent — lifts soil, blood, and product so that a disinfectant can actually reach microbes. A disinfectant poured over hair clippings, oil, or dried blood is wasted chemistry.

Disinfection is the chemical destruction of most pathogenic microorganisms on a nonporous surface. It does not reliably destroy bacterial spores. New Jersey's chemical standard is specific: a disinfectant registered by the Environmental Protection Agency and labeled as being tuberculocidal, used for the contact time specified on the product label. The Board used to allow a product labeled effective against HIV and HBV at a recommended dilution. The May 18, 2009 amendment (R.2009 d.169) replaced that HIV/HBV option with tuberculocidal labeling or an FDA-registered autoclave. Do not memorize the retired HIV/HBV shortcut as if it were still the rule.

Sterilization is the destruction of all microbial life, including bacterial spores. In a New Jersey shop, the listed sterilization device is an autoclave registered with the Federal Food and Drug Administration. Autoclaves use steam under pressure. They are not UV cabinets, not a jar of dry sanitizer crystals, and not a drawer you labeled clean. A 1990s compilation of 13:28-3.2 told licensees to store instruments in a dry sanitizer. That language is gone. Current (a)5 requires air drying and storage in a clean drawer.

The New Jersey sequence: N.J.A.C. 13:28-3.2(a)

A licensee shall sanitize all implements and tools by:

1. Cleaning thoroughly with a mild alkaline detergent to remove any soil, blood, or any other foreign material.
2. Rinsing with tap water after cleaning.
3. Processing with a chemical disinfectant registered by the EPA and labeled as being tuberculocidal for a contact time as specified on the product label, or processing in an autoclave registered with the FDA.
4. Following the manufacturer's instructions when using chemical disinfectant.
5. Allowing disinfected implements and tools to be air dried and storing them in a clean drawer.

Read (a)3 and (a)4 together. Contact time is not a number the Board invented for the exam. It is whatever that EPA-registered label requires. Shortening a ten-minute immersion because the next client is waiting is a violation of (a)3 and (a)4, even if the jar still looks blue. After the chemical step, (a)5 forbids wiping a processed shear with a used cloth that would recontaminate it, and it forbids dropping a wet shear into a cluttered station drawer.

The sequence is after each use on a patron. N.J.A.C. 13:28-3.1 requires tools applied directly to patrons to be thoroughly cleaned and sanitized after each and every use in accordance with 13:28-3.2. I disinfect at closing is not the rule.

What each step is for

Detergent in (a)1 is cleaning. The rinse in (a)2 removes soil-laden detergent so leftover soap does not interfere with the disinfectant. Processing in (a)3 is disinfection or sterilization. Manufacturer instructions in (a)4 cover dilution, whether the product is a soak, spray, or wipe, metal compatibility, and whether you rinse after the contact time. Air-dry and clean-drawer storage in (a)5 keep a processed tool from sitting in splash water or sharing a drawer with used clips.

Electrical appliances cannot survive a tap-water rinse and a soak. N.J.A.C. 13:28-3.1 still requires electrical appliances in the shop to be maintained in a sanitary and safe manner. Do not dunk a blow-dryer. Do not invent a Board-published clipper-wipe protocol that 13:28-3.2 does not print. Know that immersible multi-use implements follow (a), and that motors and cords are still part of a sanitary New Jersey shop.

Pedicure tubs: the same chemistry, written out

Subsection (c) is still 13:28-3.2. Shops that offer pedicuring must clean tubs between clients and at the end of the day. Between clients you brush the interior with a mild detergent; drain, rinse, and wipe dry with a disposable paper towel; then spray with an EPA-registered tuberculocidal disinfectant for the labeled contact time or apply a bleach wipe at a 6% concentration of sodium hypochlorite for a two-and-a-half-minute contact time. At day's end you remove, clean, and disinfect the screen, filter, and other removable parts; brush the interior with mild detergent; run a 100 PPM bleach solution (1 teaspoon of 6% sodium hypochlorite to one gallon of water) for a 30-minute contact time; and soak brushes in 2,600 PPM bleach (3/4 cup of 6% sodium hypochlorite to one gallon of water) for 30 minutes. Those dilutions are statutory. They are not about a capful.
